A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...

Many noise sources can plague high-speed radio-frequency (RF) analog signal chains, making design considerations that much more challenging. Both megahertz and sub-terahertz sampling-rate converters ...

When you’re hunting for a signal with your oscilloscope, the stronger it is, the better. If it’s weak, you might struggle to tease it out from other interference, or even from the noise floor itself.
